atmosphere or may be connected with the tires of an automobile or a separate reservoir, as desired. Interposed in the induction pipe 20 is a three-way valve 24, the third port of which communicates with a nipple 243, this nipple also being in communication with the atmosphere, as shown. The; stems of the three-way valves 28-24 ai'e joined by a link 25 which insures simultaneous operation of the valves so that when said valves are in the position shown in the drawing, gasolene vapor is taken from the carbureter through the pipe 20, and forced through the pipe 21 into the reservoir 22. hen, however, the. positions of the valves 23 and 24: are reversed, communication with the carbureter and with the vapor reservoir 22 is cut oii', and the nipples and 24* are connected with the pump so that it may be run idly or employed for compressing atmospheric air, as the operator desires.

Arranged in the vapor reservoir 22 is a perforate outlet pipe 26 which passes vertically to the upper part of the reservoir and communicates outside of the reservoir with a pipe line 27 having branches 28 passing re spectively to the chambers 14; of the valve housings 11, so that the communication between said branch pipes 28 and the interior of the cylinders is controlled by the admis: 'sion valves 12. The pipe 27 is provided with a check valve 29 preventing the return to the reservoir 22, and similar check valves 30 are arranged in'the branch pipes 28. The pipe 27 also carries a valve 31 having attached to its stem an arm 32. With this arm coact-s the curved finger 33 of a lever 34, which is in connection with the reach rod 1?, so that as the lever 18 is thrown leftward from the position shown in the drawings, not only will the admission valve 12 be opened, but through its finger 83 the lever 34 will swing the arm 32 of the valve 31 and open the valve, this valve being closed during the inaction of the starting mechanism. As the lever 18'is returned to the position shown in the drawings to permit the springs 16 to close the valves 11, the finger moves away from the arm 32 of the valve andlcaves the valve open. Said valve may be subsequently closed at any time when it is desired to cut the starting mechanism out of operation. As shown best in Fig. 2 the oranch pipes 28 enter the housings 14, and have nozzles 28 arranged to deliver a jet diagonally through the valve seat, past the spark plug and into the cylinder, insuring the entry of the charge against atmospheric or other pressure that may be present in the cylinder and tending also to cleanse the spark plug. This disposition of the nozzles 28 serves also to create a suction in the chamber 14 and in the induction line connected therewith, thus assisting the normal operation of the carbureter.

In order to prevent the passage of the spark when-the'admission valves are open and avoid the danger of back firing in the pipe 27 and branches 28, I arranged contacts 35 in connection with the lever 18 in such a manner that as the lever is thrown leftward to lift the valves the primary or other circuit of the igniting system will be broken, thus preventing the development of the spark. As soon as the lever 18 is returned to the position shown, the contacts re-engage and the circuits close, permitting the operation of the sparking mechanism in the normal manner.

If desired the apparatus may be fitted with means for automatically cutting out the pump action as compression in the reservoir reaches the desired point and to avoid such compression as might render ignition within the chamber possible. These meansmay be of any desired sort; as here shown they consist in. a pressure cylinder 35 fitted with a piston and regulating spring. The rod 36 of the piston has a fork 37 which is releasably engaged with the operating arm of the valve 23. By this arrangement as the pressure rises the valves 23 and 24: will be opened to the atmosphere, and as the pres sure drops they will be automatically returned to vapor pumping adjustment. Should it be desired to adjust the valves manually the fork 37 may be disengaged from the valve 23, leaving the valves free.

In the operationof the invention, the pump 19 should be permitted to keep the reservoir 22 charged at all times with a gasolcne vapor or other combustible mixture, so that upon stopping the engine the reservoir remains charged. In order to start the engine the lever 18 should be thrown leftward lifting the valves 12 from their seats and opening the valve 31. The ,-ompressed gasolene vapor will then flow through the branch pipes 28 and nozzles 28 and said nozzles will cause the rich vapor from the tank 22 to be thrown in a jet past the spark plugs the working cylinders and into the interiors thereof completely charging the cylinders of the engine, notwithstanding that some pressure may exist in the cylinders. When this has been done the lever 18 should be returned to its seat allow ing the valves 12 to close and cut off the pipe branches 28 from communication with the interior of the cylinder. Then by properly adjusting the sparking mechanism or other igniting device and passing the spark within the cylinder or cylinders, the piston 01 pistons of which are in working stroke positions, explosions will be caused in said cylinders and the gases of combustion acting 7 tancouslv o )onin said val ran on the said pistons will impart a moven'ient to the engine. The operation of the engine then becomes normal, the charges being drawn from the carbureter in the usual manner through the chambers 1t and their con nections (not shown) and these charges being" supplemented by charges admitted through the pipes 28 from the vapor reservoir 22, the pump 19 acting continuously to recharge the reservoir. The engine may be allowed to operate in this manner as long as desired. Usually, however, upon the operation of the engine becoming normal the valve 31 should be closed, thus cutting out the auxiliary starting apparatus. If on an occasion of excessive load upon the engine, or other severe conditions, it is desired to accelerate the op eration, the valve 31 may be manually opened admitting the extra charge from the branch pipes 28. The reservoir 22 should be fitted with a suitable gage, and the action of the pump 19 should be so regulated as to prevent development of excessive pressure in the reservoir. As the pressure becomes excessive the valves 23 and 2& may be operated either manually or automatically to cut the reservoir and carburetor out of communication with the pump.
